I don't have functions like inv, pinv, det - build problem?

[Hakan Yüksel]

Hello,

I have configured and compiled octave-2.1.73 with following options:

      ./configure --prefix=/usr \
                  --with-blas \
                  --enable-shared \
                  --with-hdf5 \
                  --enable-rpath \
                  --with-lapack \
                  --disable-nls \
                  --enable-readline \
                  --enable-picky-flags \
                  --with-g77 \
                  --with-x

      make
      make install

Gcc version is 4.1.1.

When I want to call det(A), inv(A) or pinv(A) I get the following line:
"error: `inv' undefined near line 8 column 1".

I have noticed that I don't have 
/usr/lib/octave/2.1.73/oct/<platform><os> with files like inv.oct, 
pinv.oct, det.oct and so on inside. There is not even the folder 
/usr/lib/octave. It seems to me that something has to be different in my 
call to configure. But what?

Thank you.

With king regards
Hakan
